The power cord pulled out of the 4 pin amphenol power plug. This is the black plastic connector that cord to the dolphin to the actual power supply. The cord from the dolphin has two wires - 1 black, and 1 white. The four pin connect has four place you can insert wires they are numbered 1, 2, 3, 4. Which wires go to which numbered hole?
ADMIN REPLY: Normally, White to 1, Black to 2. To be certain, look at how the socket on the power supply is wired.
